Struct ValueDictionaryConfig 

pub struct ValueDictionaryConfig {
    pub low_cardinality_threshold: usize,
    pub min_len_for_dictionary: usize,
}

Value dictionary tuning parameters.

Fields

low_cardinality_threshold: usize

Maximum unique cardinality per field before dictionary encoding is disabled.

min_len_for_dictionary: usize

Minimum byte length before dictionary encoding is considered.

Trait Implementations

impl Clone for ValueDictionaryConfig

fn clone(&self) -> ValueDictionaryConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ValueDictionaryConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ValueDictionaryConfig

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for ValueDictionaryConfig

fn eq(&self, other: &ValueDictionaryConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
